specting the fertility of a piece of land at Wantage, in 
Berkshire, published in the Bath Agricultural Transactions, 
it is stated that the land was let at £14 per acre, and pro- 
duced enormous crops without manure while under the 
plough, and most superior pasture when laid down to grass, 
in which state it had been for several years when the soil, 
and subsoil, and that of an adjoining meadow were analysed 
by Mr. Boyd. The soil of this excellent land contained 6 
per cent, of alumina, the subsoil 5.2, and the soil of an ad- 
joining meadow 5.5 (Bath Philos. Trans.) 
An excellent pasture analysed by Sir H. Davy, from the 
banks of the Avon, in Wiltshire, contained of alumina 6.2, 
chalk 6.3, siliceous sand 9 per cent — (Johnston on Manures, 
p. 262.) 
The soil of a rich natural pasture at Endsleigh, in Devon- 
shire, which fattens on an average a bullock of 160 stone, 
and winters two sheep, contained 8^ per cent, of alumina, 
with no lime in it ( Ibid, p. 241.) 
A rich ancient pasture near Croft Church, in Lincoln- 
shire, contains 6.1 alumina (Ibid, p. 244. J 
Woburn Abbey Park, which produces the finest oaks in 
England, 7 J alumina. — (F. S. Planting, p. 49.J 
To which may be added two excellent soils from Craven, 
given and analysed by J. Spence, both producing feeding 
pastures, — the one on the Millstone Grit containing alumina 
5 per cent., and the other on one of the Chert beds 6 per 
cent, of the same earth. 
The soil of the Lias in the district we are now describing 
contains 7 per cent, of alumina;* and it is well known that 
upon this stratum are found the best grazing pastures of 
* Lias clay from Bellthorp (best grass land of the district) : —
